I’m sure a lot of people have gotten this code before, and I wanted to know if it’s worth going thru all the trouble and most importantly money/time to get this fixed or if it’s better to start looking to sell the equipment and get another newer truck. I’ve got a 2015 Cascadia Evolution automatic smart shift, and it’s a great and convenient truck, but this nox problem I heard is notorious among these Detroit engines. I want to hear your thoughts.
Thanks,

Piece of black tape over the light,,,I'm sorry, people have called me a troll for comments like that, nothing could be further from the truth. I really have no idea and can't for the life of me understand why you people put up with that junk. I get "Truck Paper" notifications all the time, there was a '78 KW W900, day cab, 400 BC , 13, and air ride, in great shape, asking $15g's. Why would someone spend 10 times that for a modern POS?

Ya, it’s a catch all code for low NOx efficiency. It can be just about anything. I’ve had it since winter, mostly first thing on a Monday morning. I have Detroit Diesel Diagnostic Link, so I can eliminate some of the steps without going to the dealer. One of the early steps it said to replace the outlet NOx sensor as it was reading low. But that didn’t help.
I did notice if I did a forced Regen the code wouldn’t pop up for several weeks. Which could be an indication that I needed a DEF awning kit. My DPF filters I knew were coming up soon, so I waited a few months for when the Soot full code came up. Which was only just over a week ago. I had them install the DEF awning kit at the same time.
I’ve only ran the truck for four days so far, but its been fine so far. But I’ll know for sure in about a month.
If not, then the inlet NOx sensor is the next step. And so on, trading off the truck does get tempting at some point. -

Thanks, I tried doing it, but it doesn’t let me. Good thing you don’t have to put up out of pocket cash for the repairs. Thinking about switching to company driver myself.

First you need to sign up for a Single Sign-on ID.
Then with the ID sign on to Nexiq site,
to purchase the adapter and a subscription to the software.
DiagnosticLink: Home
It’s $500 a year for the software, only the standard edition is available. You can modify some of the engine parameters and do full diagnostic routines. You cannot reprogram engine power, fuel mapping, etc. Requires the professional version. Also you cannot set Cascadia Sam Cab or chassis parameters.
You can use the Nexiq USB 2 adapter or a Dearborn DPA5 adapter with DDDL. Heavy Duty Diagnostic and Reprogramming Vehicle Scan Tool for Diesel Truck, Medium Duty and Automotive Technicians
